Free SEO audit — FAQ

Is the free SEO audit really free?

Yes — unlimited public scans, no signup, no credit card. We make money on Pro plans (auto-fix, scheduled monitoring, AI visibility); the audit itself stays free forever.

How long does the audit take?

Around 30 seconds for a single page, 1–3 minutes for a 100-page crawl. We use parallel workers and Google's official Lighthouse engine so the wait is real, not artificial.

What exactly does the audit check?

140+ signals across eight categories: meta tags, indexing & crawl, performance (Core Web Vitals: LCP, INP, CLS), structured data (JSON-LD schema), internal & external linking, content quality, mobile-friendliness, and HTTPS/security headers.

Will the audit affect my live site?

No. The free audit is a read-only crawl — we fetch the same public HTML Googlebot does. Auto-fix only writes to your site after you explicitly connect WordPress and approve each change.

Can I audit any website, or only mine?

Any public website. Audit competitors, prospects, client sites, or your own. There's no domain verification required for the read-only scan.

How accurate are the Core Web Vitals numbers?

We run the same Lighthouse engine Google uses in PageSpeed Insights. Numbers reflect a clean synthetic crawl — real-user data from CrUX can vary and is surfaced separately for verified sites.

Does it work for non-WordPress sites?

The audit works for any public website — WordPress, Shopify, Webflow, Ghost, Squarespace, custom React/Next, Hugo, Jekyll, anything. One-click auto-fix is currently WordPress-only; Webflow + Shopify are in beta.

How is FreeSEO different from Screaming Frog or Ahrefs Site Audit?

Screaming Frog requires a desktop install and only outputs raw data. Ahrefs Site Audit starts at $129/month. FreeSEO is browser-based, free, and pairs findings with one-click WordPress fixes — audit and remediation in one workflow.

Stop guessing. Start fixing.

Your competitors are already auditing weekly. Run yours now — it's free, forever.
